2. Noncommunicable diseases can spread from person to person. Communicable diseases cannot spread.
3. Noncommunicable diseases are caused by bacteria. Communicable diseases are caused by viruses.
4. Communicable diseases are caused by bacteria. Noncommunicable diseases are caused by viruses.
Answer:
Step-by-step explanation:
The main difference between communicable disease and non-communicable disease is that Communicable diseases are those diseases that can spread from person to person, whereas, non-communicable diseases are those which do not spread and are non-contagious. Communicable Disease v s.
Communicable diseases are those that are contagious but generally short-lived. Noncommunicable diseases are not contagious and can’t spread to other people; these are chronic illnesses. While communicable diseases are caused by pathogens such as bacteria and viruses, noncommunicable diseases are generally due to genetics and lifestyle.
Answer:
I believe your answer is 1. Communicable diseases can spread from person to person. Noncommunicable diseases cannot spread.
Step-by-step explanation:
Communicable diseases are the diseases which passes from one individual to another individual. They are generally caused by some bacteria, viruses or any other pathogens. For example, malaria, AIDS etc. Non-communicable diseases are the diseases which does not spread from one person to another person.

What is a force of attraction between an object and the earth due to gravity?
Newton's law of gravitation says that the force due to gravitation between two objects with masses m₁ and m₁ is given by the formula
[tex]F=G\dfrac{m_1m_2}{r^2}[/tex]
Where r is the distance between the objects, and G is the gravitational constant (about 6.674×10⁻¹¹ m³⋅kg⁻¹⋅s⁻²)

Question 6(Multiple Choice Worth 4 points)
(05.07 MC)
The number of wins for a high school football team is measured for the season. When the team plays at home, it is generally believed that they will win. Comparing the location of the game and the number of wins, a correlation coefficient of 0.891 is calculated. What would this imply about the football team winning at home?
The scatter plot would closely resemble a straight line with a positive slope. The data has a strong, positive correlation, but causation cannot be determined.
The scatter plot would closely resemble a straight line with a positive slope. The data has a strong, positive correlation, and a causal relationship exists between the team playing at home and winning.
The scatter plot would not be represented by a line of best fit with a positive slope. There is a weak correlation between the football team playing at home and winning.
There is no causation and almost no correlation between the football team playing at home and winning.
Answer:
The scatter plot would closely resemble a straight line with a positive slope, but causation cannot be determined.
Step-by-step explanation:
Recall that causation and correlation are 2 different things. Say Taller people usually had a name that started with the letter “A” It's a correlation, but a name does not determine the height, so it's not causation. (I took the test and got it right too.)
The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning would be imply about the football team winning at home.
What is a correlation coefficient?It is an index that measures correlation between two variables, assuming values between -1 and 1.
If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
It also is the slope of the line of best fit.

Point (7,12) is rotated 1260° counterclockwise about the origin. What is the X-coordinate of the point after this rotation?
Given:
Point (7,12) is rotated 1260° counterclockwise about the origin.
To find:
The x-coordinate of the point after this rotation.
Solution:
If a point is rotated 360 degrees then its coordinates remains unchanged.
If a point is rotated 180 counterclockwise about the origin degrees, then
[tex](x,y)\to (-x,-y)[/tex]
We know that,
[tex]1260^\circ=1080^\circ+180^\circ[/tex]
[tex]1260^\circ=3\times 360^\circ+180^\circ[/tex]
After [tex]3\times 360^\circ[/tex] rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.
[tex](7,12)\to (-7,-12)[/tex]
The point (7,12) becomes (-7,-12) after rotation of 1260° counterclockwise about the origin.
Therefore, the x-coordinate of the required point is -7.

Subtract equation two 3 digit numbers with different hundreds digits and a difference of less than 100
Answer:
690 - 595
Step-by-step explanation:
As we know that representation of a 3 digit number = xyz
where x [tex]\neq[/tex] 0
z is at ones place
y is at tens place
x is at hundred place
As, we have to subtract two 3 digits numbers with different hundred digits
So, Let
The hundred digit of first number be 6
The hundred digit of second number be 5
∴
Assume first number with hundred digit 6
Let the number be - 690
Now,
Assume second number with hundred digit 5
Let the number be - 595
Now,
We will check that the difference between both the numbers are less than 100 or not
Now,
690 - 595 = 95 < 100
It satisfies the condition
So, the equation becomes 690 - 595
A is directly proportional to B squared
When A= 500, B = 10.
Find A when B= 20.
Answer:
A = 2000.
Step-by-step explanation:
A = kB^2 where k is a constant to be found, so substituting:
500 = k * 10^2
100k = 500
k = 5.
So we have
A = 5B^2
When B = 20:
A = 5 * 20^2
= 5 * 400
= 2000.

Answer:x=2
Step-by-step explanation:
Consider that lines u and vare parallel. Which equation models the relationship between the angles? What is the value of x?
[tex]\color{plum}\tt \: \bold{(A) 12x - 4 = 10x + 10 ; x = 7}[/tex]
Steps to derive the correct option :Given :Lines u and v are parallel Measure of an angle = 12x - 4Measure of it's corresponding angle = 10x + 10Since these angles are corresponding angles and lie on two parallel lines, their value will be equal.
Which means :
[tex] = \tt12x - 4 = 10x + 10[/tex]
[tex] = \tt12x - 4 - 10x = 10[/tex]
[tex] = \tt12x - 10x = 10 + 4[/tex]
[tex] = \tt2x = 14[/tex]
[tex] =\tt x = \frac{14}{2} [/tex]
[tex] =\color{plum}\tt x = 7[/tex]
Thus, the value of x = 7.
Let's place 7 in the place of x and see if their value matches :
12x - 4[tex] = \tt12 \times 7 - 4[/tex]
[tex] = \tt84 - 4[/tex]
[tex] = \tt80[/tex]
Thus, ∠12x - 4 = 80°
10x + 10[tex] =\tt 7 \times 10 + 7[/tex]
[tex] = \tt70 + 10[/tex]
[tex] = \tt80[/tex]
Thus, ∠10x + 10 = 80°
Since the value of these two angles are equal, we can conclude that we have found out the correct measure of each angle.
Therefore, the correct option is - (A) 12x - 4 = 10x + 10; x = 7
